While Elixir is becoming a popular language for web development, there is at least one topic that I still find lacking: Deploys.

Whenever a web app has integrations with external APIs (which, let’s face, happens most of the time nowadays), there’s usually an increased complexity about it when it comes to testing.

Code golf is an interesting concept to me: to solve a programming challenge, using not the most efficient or readable code, or the most state-of-the-art solution, but with the smallest code size possible.

With recent advances in front end technologies, front end developers have been going crazy, pushing CSS to its limits and doing all sorts of beautiful animations. Seriously, there are some crazy things out there.

Mobile web applications are expected to work differently from desktop applications. They need to feel responsive to the user’s touch. Having worked on a couple of mobile web applications in the last year, I found that I always start by changing the browser’s default appearance and behaviour. This article contains my setup to make a mobile web application feel more like a native one.

In the last couple of months I’ve been a part of Group Buddies. I joined this company as an apprentice, where I learnt how to work for the web and to follow high quality standards. I was already coding apps for fun, but I had no idea how the web worked.

I’m taking the time to write the tutorial I wish I had some months ago. My task was to set up some user voice recording mechanism in the browser. It should record for about one hour, non-stop, saving to a server. The idea was to use the [getUserMedia()][getusermedia] API. No browser extensions should be used.

Having written and read a lot of Ruby code, I occasionally come across some not-so-well-known features. Or even just a tiny detail that, as useless as it may be, I still find interesting.

Like most developers I know, there is a list of things I want to learn and experiment with. Mobile development was on the top of that list until last December, when we took a day off for an internal hackathon and some of us got to work on a mobile app.

It’s an almost impossible task to find a way to write consistent, future-proof and robust CSS. Our process has, until recently, consisted of appending CSS rules in an ad hoc manner to some sort of file organization.

If you were ever in charge of configuring a web server, you must know how painful it can be sometimes. During your first learning days, you probably spent an awful lot of time SSH’ing into the server, trying out something you just found online. It probably ended up being a slow trial-and-error process before you got your first server up and running.

One of the hottest topics of the moment in the rails community is application design or architecture. There is an obsession (a good one, I think) with clean, decoupled code, that is easy to maintain and extend. This has led to things such as presenters, service objects, to some extent even rails concerns.

If you’ve been in the development business for a while, especially if working with OO languages, you’ve probably heard of design principles. It’s kind of hard to keep track of them all, and sometimes it is even impossible to follow them all. That’s why, as with many things in the software area, you should use these principles as guidelines, not rules.
